DOOR LATCH Filed Feb. 16. 1927 I vPatented .lanQZO, 1931 I 'HARLsoN E.130133, JR; or LuZ E RN IOWA- i I noonLA 'rcn Application filed February16 1927.: serial-no. 168,561

Still a further object is to provide a latch j which, when applied to asliding door, will have a tendency to engage more firmly in an I eyewhich is secured to the frame of the dooi n Still a further object'is toprovide such a I latch which can be secured to the door in po sition to,move by gravity to a position where no parts of the device projectbeyond the edge of the door when the door is unlatched.

Still a further object is to provide means on the latch for utilizing apadlock for looking the latchagainstbeing opened. With these and otherobjects in view, my invention consists in the I construction,arrangement and combination of the various parts of mydevice, wherebythe objects contemplated are attained, as hereinafter more 1 fully setforth, pointed out in my claim and illustrated in the accompanyingdrawings, in which: I

Figure 1 is a perspective view of'the parts embodying my latch; V

Figure 2 is an elevation showing the latch attached to a door and inlatched position. Figure 3 illustratesthe device applied to a door andin unlatched position; and a Figure' is an enlarged elevation of thevent the latch from being unlatched.

On the accompanying drawings I have used the reference numeral 10 toindicate a supporting bar. The supporting bar 10 is formed with a pairof openings 12 for the purpose of receiving screws orboltswhereby thesupporting bar :is secured to a door ora door frame. I f 1 I Figure 2illustrates thesupporting bar 10 secured to a door 14 by bolts 16. I

Pivotally mounted on the supporting bar 10 is a latch bar 18. Thelatchbar 18 is rotatably mounted on arivet or the like 20 which extendsthrough both the supporting bar 10 and the latch bar 18. A washer 22 isdevice showingthe use. of a padlock to pre- 'ject to catching harness onhorses as porting bar for the purpose of preventing anytbinding of theparts. It is, of.cour'se, understood that: the. rivet 20 is'riveted'sufficiently loose for the purpose of allowing ree pivotal movement ofthe latch bari'18 on the rivet 20. 1 1

The" latch 24,:the side 26 of which is: formed at anangle "relativeto,the bar 18. The purpose'of soforming the side 26 of-the notch 24 wi11 v.

hereinafter be more fully described; 1

The outer end oftheilatch' bar-1 interposed between the'latcli bar andthe supi I 18 .is formed with a notch 8 is r narrower than the bodyportion thereofz-and l is bent ibaok'uponiitself for forminga handlemember 28' The end 'isthen riveted to the".

body portion of thelatch bar 18 by meansof I a rivet 30 wherebyaverysatisfactory handle is formed, p or s i A downwardly projecting, hookmember 32 is formedtbeyond the notch '24-. The) hook member 32 is:provided with "an opening 3% 'for'receiving'a padlock. The hookmember32 is designed to. en- '25 gage an eye member 36 which is substantiallyI angle shaped and is provided with openings 38; ,xThe' eye--member--36is secured to the door frame; orv the door as v the casemay, be

through the '1 openings .38. The upper out- I wardlyproj'ecting"portionof the eye inemby'means ofkbolts orthelikellO extending l so ber 36isformed. with a slot opening 42 for the purpose ofreceiving the hookmember 7 32of'the latch bar 18.,'. I

The supportingbarxl0 and the eye member 36 are attached' ,to a" doorandframe 4 1' of. a barn or-ithe -like as clearly illustrated in 7 Figures2 and 3 of the drawings. It will bar 10 is be noted that the supportingspaced fromzthe edge of the door 14 so that when the. latch bar 18 is inunlatched position it will by gravity hang downwardly and i will notpresent any parts projecting beyond the edge ofthe door. This positionis clearly illustrated in Figure 3 of the'drawings.

The desirability of such construction lies in the fact that" anyprojecting parts are subthey pass into the barn or the like. a

It will be noted that the slanting side 26 of the notch 24 when the hookmember 32 is insertedthrough the opening 42 will have a tendency to pullthe latch bar. 18 downwardly if the door 14 is moved away from the doorframe 44 when the latch is This prevents any: possibility of the latchcoming unlatched when an attempt is made to open the door withlatchedposition.

From the .ioregoing. descni :tion it is .obvious that I have provided alatch .which in normal unlatched position will not presentvanyedgesoricornersto be caught oniobiects passing through the ibarn door.opening. .Means zhasfbeen provided to prevent from the eye member.3'6-when an attempt is madeto openthe door.

'Somerchanges may bemade in the construction and arrangement of thevarious parts of my invention, Without departing from the real spiritand :purposeof my invention, and it is my intention to cover by my:claim any modified'forms of structureor use of mechanicalequivalents,which may be reasonably included withintheir scope:

I I claim as my invention:

A door latch comprisingv a supporting bar, a latch bar of 'flatbarmaterialpivoted thereto, a notch insaid latch bar adjacent the endthereof, whereby a downwardly "extend.- ing' hook isiprovided, aneye-member for said hook, the side'o'f said notch farthest from thepivotal point of said latch bar being cut at an angle whereby .pnll onthe latch bar tends to maintain the hook within said eye member and-ahandle for said latchbar'bom prising a portion of the 'barbeyondsaidhook redoubled upon andisecured to itself.
